FSX Cockpit Sounds For ND AW-109. The archive contains two gauges for the Nemeth's AW-109. One adds sounds for each single switch, lever and button to make the cockpit alive. The other will allow a true cold and dark start. All switches and engines will be OFF when the helicopter is loaded. A new start procedure is included. You can choose either to install both of them or only one. By Daniel Gauthier.
